Description

Technical Field

[0001] The invention belongs to the technical field of curtain wall glass frames, and in particular relates to a nearly zero-energy consumption building curtain wall glass frame. Background Art

[0002] The design and implementation of near-zero energy building curtain walls is an important part of near-zero energy building technology. It is of great significance to reduce building energy consumption and improve energy utilization efficiency. Energy-saving curtain walls mainly include double-layer curtain walls, ventilated double-layer curtain walls (heat channel curtain walls), ecological curtain walls and low-carbon curtain walls.

[0003] For example, the utility model patent with patent application number 200920219857.7 discloses a keel ventilation double-layer glass curtain wall, which adopts a vertical keel structure with a continuous inner cavity; the air outside the bottom of the vertical keel is connected to the atmosphere outside the air outlet through the inner cavity of the vertical keel, and the air in the vertical keel continuously flows upward from the bottom to achieve the ventilation effect by using the "chimney effect". This structural setting allows air to enter the inner and outer glass interlayers of the double-layer glass through the open window, and then enter the vertical keel through the ventilation hole; during this flow process, dust will inevitably enter the inner glass interlayer, causing the inside of the glass to be contaminated and difficult to clean.

[0004] The frame of the curtain wall glass is usually provided with a shutter-like structure, such as a foldable cavity curtain wall disclosed in the invention patent with patent application number 201910557334.1. Although the structural setting of this structure of shutters can play a good role, its structural setting will greatly affect people's vision. In addition, the setting of shutters has poor wind resistance, especially in the current situation of high floors.

[0005] At the same time, existing curtain wall glass often requires a lot of manpower in the later cleaning process, which poses certain risks. Summary of the invention

[0006] In response to the above technical problems, the present invention provides a nearly zero-energy building curtain wall glass frame, which is provided with a ventilation structure that can switch the ventilation route without circulating through the internal glass interlayer; the shading mechanism can reduce the obstruction of the field of vision, and has cleaning and fixing functions, thereby improving the ability to cope with strong winds.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0008] A nearly zero-energy building curtain wall glass frame, comprising a connecting frame and a sunshade mechanism; the connecting frame comprises a longitudinal keel and a transverse keel, the transverse keel is fixedly connected to the longitudinal keel; a first ventilation hole is provided on the outer side of the longitudinal keel, a second ventilation hole is provided on the inner side of the longitudinal keel, a ventilator is provided on the longitudinal keel, and the second ventilation hole is communicated with the first ventilation hole or the inner cavity of the longitudinal keel by adjusting the ventilator;

[0011] The first driving mechanism adopts a reduction motor; the output shaft of the reduction motor is fixedly connected to the rotating shaft; the housing of the reduction motor is fixedly connected to the connecting frame.

[0012] The second driving mechanism comprises a driving wheel and a driven wheel; the driving wheel and the driven wheel are respectively hinged to the scraper through swing arms, and a tension spring is arranged between the two swing arms; and the pull rope is located between the driving wheel and the driven wheel.

[0013] The driving wheel adopts a hub motor.

[0014] A rubber scraper strip is fixedly connected to the scraper; and a water spray pipe is arranged on the connection frame.

[0015] The ventilator includes an outer shell and a rotating drive shaft; the second ventilation hole is connected to the first ventilation hole through the outer shell; the rotating drive shaft is fixedly connected to the outer shell; a sealing plate and a dustproof plate fixed in a cross shape are fixed on the rotating drive shaft; a connecting hole connected to the inner cavity of the longitudinal keel is provided on the top of the outer shell, and a baffle for covering the connecting hole is slidably connected to the outer shell; a transmission mechanism is provided between the rotating drive shaft and the baffle.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0037] like Figure 1-12 As shown, a nearly zero-energy building curtain wall glass frame includes a connecting frame 1 and a shading mechanism 2; the connecting frame 1 includes a longitudinal keel 100 and a transverse keel 101, and the transverse keel 101 is fixedly connected to the longitudinal keel 100, specifically by bolts or welding; the longitudinal keel 100 also adopts an integrally connected connection setting.

[0038] The longitudinal keel 100 is provided with a first ventilation hole 102 on the outside, a second ventilation hole 103 on the inside of the longitudinal keel 100, and a ventilator 3 is provided on the longitudinal keel 100. The second ventilation hole 103 is communicated with the first ventilation hole 102 or the inner cavity of the longitudinal keel 100 by adjusting the ventilator 3. When it is not raining, the second ventilation hole 103 is communicated with the first ventilation hole 102 by adjusting the ventilator 3 to achieve indoor and outdoor air circulation. When it is raining, the second ventilation hole 103 is communicated with or the inner cavity of the longitudinal keel 100 by adjusting the ventilator 3, and the chimney effect is also used to make the air flow through the bottom of the longitudinal keel 100, through the inner wall of the longitudinal keel 100, and finally lead out through the ventilation structure provided on the top of the longitudinal keel 100.

[0039] The sunshade mechanism 2 includes a telescopic sunshade 200 and a scraper mechanism 201; the telescopic sunshade 200 is rotatably connected to the connecting frame 1, and a first driving mechanism 202 is provided at the rotating connection, and the telescopic sunshade 200 is driven to rotate by the first driving mechanism 202. When shading is required, the telescopic sunshade 200 is extended, and its extended length can be adjusted as needed; at the same time, the first driving mechanism 202 can be used to adjust the inclination angle between the telescopic sunshade 200 and the connecting frame 1, so as to meet the shading needs at different times. When shading is not required, the telescopic sunshade 200 is shortened, and the first driving mechanism 202 drives the telescopic sunshade 200 to rotate to a vertical state with the connecting frame 1, thereby minimizing the obstruction of the curtain wall glass and improving the field of vision.

[0040] A pull cord 203 is provided on the telescopic sun visor 200, and the pull cord 203 is in a tensioned state after the telescopic sun visor 200 is extended. When strong winds occur, the telescopic sun visor 200 is extended, and the first driving mechanism 202 drives the telescopic sun visor 200 to rotate to a parallel state with the connecting frame 1. At this time, the pull cord 203 is in a tensioned state; the scraper 204 is driven downward along the pull cord 203 by the second driving mechanism 205, so that the insert block 206 on the scraper 204 is inserted into the fixed card slot 104 on the connecting frame 1, which plays a fixing role. In this way, the influence of strong winds on the telescopic sun visor 200 can be reduced to prevent it from being damaged.

[0041] When cleaning is required, the telescopic sunshade 200 is also extended, and the first driving mechanism 202 drives the telescopic sunshade 200 to rotate to a parallel state with the connecting frame 1. At this time, the pull rope 203 is in a tensioned state; the scraper 204 is driven by the second driving mechanism 205 to move up and down along the pull rope 203. During the up and down movement, the scraper 204 contacts the curtain wall glass to clean the curtain wall glass. Water or cleaning liquid can be sprayed on the curtain wall glass in advance so that the scraper 204 can scrape the outside of the curtain wall glass clean.

[0042] Preferably, a rubber scraper 2015 is fixedly connected to the scraper 204, that is, the cleaning operation is performed by contacting the rubber scraper 2015 with the curtain wall glass. At the same time, a water spray pipe 105 can be provided on the connection frame 1; the water spray pipe 105 is connected to a water pipe, and the water pipe passes through the connection frame 1 and extends into the room. The nozzle on the water spray pipe 105 faces the curtain wall glass, and water is sprayed from the nozzle to the curtain wall glass through the water pipe.

[0043] Furthermore, the telescopic sun visor 200 includes a fixed plate 207 and a movable plate 208. The movable plate 208 is slidably connected to the fixed plate 207 and is provided with a drive cylinder 209; the drive cylinder 209 is an electric telescopic cylinder. The movable plate 208 is driven to move by the extension and contraction of the drive cylinder 209, so as to achieve the overall extension or shortening. Specifically: a rotating shaft 2010 rotatably connected to the connecting frame 1 is fixed at the upper end of the fixed plate 207; the two ends of the pull rope 203 are respectively fixedly connected to the upper end of the fixed plate 207 and the lower end of the movable plate 208. When the drive cylinder 209 drives the movable plate 208 to move and the whole is extended, the distance between the upper end of the fixed plate 207 and the lower end of the movable plate 208 increases, so that the pull rope 203 is tightened.

[0044] Meanwhile, a through hole is provided at the lower end of the movable plate 208, through which the insert block 206 can extend. When the pull rope 203 is not tightened, the scraper 204 is located at the lower end of the movable plate 208, and the insert block 206 extends through the through hole.

[0045] Furthermore, the first driving mechanism 202 uses a reduction motor; the output shaft of the reduction motor is fixedly connected to the rotating shaft 2010; the housing 300 of the reduction motor is fixedly connected to the connecting frame 1. That is, the reduction motor can drive the rotating shaft 2010 and the corresponding fixed plate 207 and movable plate 208 to rotate.

[0046] Furthermore, the second driving mechanism 205 includes a driving wheel 2011 and a driven wheel 2012; the driving wheel 2011 and the driven wheel 2012 are respectively hinged to the scraper 204 through a swing arm 2013, and a tension spring 2014 is provided between the two swing arms 2013; the pull rope 203 is located between the driving wheel 2011 and the driven wheel 2012. The tension of the tension spring 2014 is used to clamp the pull rope 203 between the driving wheel 2011 and the fixed wheel. When the driving wheel 2011 does not rotate, the movement of the scraper 204 can be restricted; and when the driving wheel 2011 rotates, it can be ensured that the driving wheel 2011 can contact the pull rope 203, driving the scraper 204 to move along the pull rope 203.

[0047] Furthermore, the driving wheel 2011 adopts a hub motor, which specifically includes a wheel body and a driving motor, wherein the housing 300 of the driving motor is fixedly connected to the corresponding swing arm 2013, and the output shaft thereof is fixedly connected to the wheel body. The driven wheel 2012 is rotatably connected to the corresponding swing arm 2013.

[0048] Furthermore, the ventilator 3 includes an outer shell 300 and a rotating drive shaft 301; the second ventilation hole 103 is connected to the first ventilation hole 102 through the outer shell 300; the rotating drive shaft 301 is fixedly connected to the outer shell 300; a sealing plate 302 and a dustproof plate 303 fixed in a cross shape are fixed on the rotating drive shaft 301; a connecting hole 304 connected to the inner cavity of the longitudinal keel 100 is provided on the top of the outer shell 300, and a baffle 305 for blocking the connecting hole 304 is slidably connected to the outer shell 300; a transmission mechanism is provided between the rotating drive shaft 301 and the baffle 305.

[0049] During installation, the shell 300 is inserted into the longitudinal keel 100 through the second ventilation hole 103, and the front end of the shell 300 abuts against the inner wall of the longitudinal keel 100 (at the first ventilation hole 102); the shell 300 is fixedly connected to the longitudinal keel 100 by bolts or the like.

[0050] When it is not raining, the rotary drive shaft 301 is rotated to rotate the dustproof plate 303 to be parallel and located between the second ventilation hole 103 and the first ventilation hole 102; the transmission mechanism drives the baffle 305 to move to cover the connecting hole 304. At this time, the second ventilation hole 103 is connected to the first ventilation hole 102, and the outside air can enter the room through the dustproof plate 303. The dustproof plate 303 is provided with a dustproof net to prevent the entry of external dust to a certain extent.

[0051] When it rains, the rotating drive shaft 301 rotates in the opposite direction, and the sealing plate 302 is placed parallel to the second ventilation hole 103 and the first ventilation hole 102, so that the second ventilation hole 103 and the first ventilation hole 102 are not connected; the transmission mechanism drives the baffle 305 to move in the opposite direction to leak the connecting hole 304. At this time, the second ventilation hole 103 is connected to the inner cavity of the longitudinal keel 100 through the connecting hole 304. External air enters through the bottom of the longitudinal keel 100, and passes through the inner cavity of the longitudinal keel 100 and is discharged from the top of the longitudinal keel 100; during this flow process, the indoor air can enter the longitudinal keel 100 through the connecting hole 304 to achieve ventilation. In this way, it is possible to prevent rainwater from entering while ventilating.

[0052] Furthermore, the transmission mechanism includes a driving gear 306 and a driving rack 307. The driving gear 306 is fixedly connected to the upper end of the rotating driving shaft 301. The driving rack 307 is fixedly connected to the baffle 305, and the driving gear 306 is meshed with the driving rack 307. That is, pushing the baffle 305 can drive the driving rack 307 to move, and the rotating driving shaft 301 is driven to rotate through the meshing of the driving rack 307 and the driving gear 306.

[0053] Furthermore, in order to facilitate pushing the baffle 305 , a shift plate 308 is fixed on the baffle 305 , and the shift plate 308 passes through the connecting hole 304 and extends into the housing 300 .

[0054] Furthermore, in order to improve the sealing performance, a sealing gasket 309 is fixed to the front end of the housing 300 .
